10 points per standard on SBG

This change seems to be working out for me.  I was using a 4/4 scale which went to 5/5 when the student has received two 4/4's.  I changed to 9/9 which goes to 10/10 with two 9/9's.  I think this is working, I like being able to grade with more detail on what I take points off for.  I think the pure way to do SBG is that four points lets you know levels like "no skill", "some skill" "proficient" and "mastered", but I'm doing a hybrid set up where the average of the SBG grade counts for 70% of a regular, old numerical report card grade and I think 10 points per standard works better in that system.
